PROPORTIONING APPARATUS.

Application filed March 10, 1927'.

My invention relates to an apparatus designed primarily for use in street and road work and the object thereof is to provide an eiiicient apparatus in which material of different grades "an be placed and from which defined quantities of each grade may be drawn, and then mixed as required by street or road specifications. A further objectisto provide an apparatus for that purpose which can be partially and quickly disassembled to a transportable condition on a railroad car or on a motor truck and quickly reassembled at a new place of use.

In the drawings forming a part of this application, Fig. 1 is a perspective of my apparatus in its operative position. Fig. 2 is perspective of certain of the parts shown in Fig. 1 in a partially disassembled position on a motor truck ready for transportation. Fig. 3 is an enlarged section on the line 3-3 of Fig. 2. Fig. 4; is an enlarged section on the line as of Fig. 1. Fi 2 is a perspective View of a slight modification of certain parts.

Referring to the drawings, 5 is a boxshaped receptacle with an open top of the capacity required by the work and will be called the bin bottom. The top of 5 is reenforced by buck stays 6. The buck stays are connected by a suitable number of tie rods 7. These buck stays are preferably formed of two U-shaped channel irons placed back to back and spaced for the passage therebetween of the tie rods as best shown in Figs. 3 and 4:. The inner sides of these members are connected to the bin bottom by rivets 8 or other means. At each tie rod the outer edges are united by tie rod plates 9 which are connected by rivets 10 to the members. Upon the bin bottom is the bin top which is composed of members which preferably flare outwardly. The end members at the bottom are riveted to the buck stays, as best shown in Fig. 4, and are of less width at the top. The side'members are re-enforced at the bottom by, what may be termed, rocking plates 11, which are riveted thereto but project below the sides and have their projecting ends bent away from the plane of the sides and form a rocking connection with the upper edge of the bin bottom, as best shown in Fig. 3. The side members of the top at each end have riveted thereto filler plates 12 which fill the spaces between the end members and the side mem-- Serial No. 174,402.

here when positioned for use. These filler plates are detachably connected to the end. members by bolts 13. hen the apparatus is to be transported through a bridge, bolts 13 are ren'ioved and t e sides are rocked to a vertical position. The bottom of the bin is secured to a stiffening frame At each corner of frame 1!) on the end sides is secured the body member 16 of a jack. Through these jack bodies extend the cor ner posts which are H-shaped and have socured to the web and in the channel a rack 17 with which the movable members of the jack engage in a well known manner to raise and lower the bin. Posts on each side are braced by diagonal braces 18 and 19 which are connected at their centers to gusset plate 20. A center post 21 at each side passes through guide lugs 2]. connected to frame 15. The corner and center posts have detachably connected to their bottom ends, feet 22. At each end is an operators frame which consists of a brace 23 at each corner which is secured to frame 15 and a cross board 24 on which the operators stand when the bin is raised or lowered. The bin is divided by partitions into compartments of which there are as many as there are different grades of material to be mixed. From each compartment is a chute 25 that, when opened,- discharges the material from the compartment into the hopper 26 of the weighing machine 27 that is detachably con nected to the bottom of the bin. In some cases a measuring device would be used instead of the scale.

It will be understood that bin bottom 5 is of a width to pass through bridges and the bin top flares outwardly to provide capacity and that when positioned for use the top is too wide to be transported through the bridges on a railroad or on a wagon road, and for that reason, I have madethe sides rockable so they may be rocked toa vertical position and thus be transportable through bridges. l Vhen in operative position, the bin and scales are elevated so that by rocking the side members of the bin top to the vertical and by disconnecting the scales and feet of the posts and end braces, I am able to lower the bin so that it may rest upon truck 28 in which condition it may be transported through covered wagon bridges without further dismembern'ient. The de tached parts can be placed in the bin or on another truck. hen the bin transported to its new place of use it can be quickly reassembled as the major parts are in operative assemblage. This is a Very desirable feature, as in road work the proportioning devices must be removed frequently from place to place. lVhen the device must be transported by rail, the corner and center posts must also be detached but that is easily accomplished as when the feet are off the posts, the corner posts may be lifted out of the jack bodies and the center posts are dis connected from frame 15.

In Fig. 2 I have shown a slight modification of the construction shown in Fig. 2. In this construction the bin bottom. and side and ends are of the same CODSUUiftiOI'l. At each corner are posts 29 of Hshaped construction which pass through gusset plates 30, which plates are secured to the bin bottom 5 on the sides thereof. Intermediate posts 29 are H-shaped center posts 31 which have secured to their webs a rack The movable members of the jacks engage with these racks in the well known manner to raise and lower the bin. Posts 29 and 31 have diagonal. braces 33 extending between them as shown in Fig. 5. In all other re spects the construction is the same as that shown in the other figures. While I have shown the bin bottom having its side and end walls vertical as to the bottom, it will be understood that these walls may be flaring or angular as to the bottom it desired. The partitions 34 are shown in dotted lines in Fig. 1.

Having described my invention, I claim- In a proportioning apparatus a bin having; a bottom and top members the end members being of the same length as the Width of the. bin bottom, the side members being rockably mounted on the bin bottom and having filler members attached thereto, said filler members being adapted to be detachably secured to the end members.

In witness that I claim the foregoing I have hereunto subscribed my name this 2nd day of March 1927.
